FAQ

What is the maximum operating frequency and corresponding performance of the R5F100CCGLA#U0?

The R5F100CCGLA#U0 achieves a maximum operating frequency of 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition. The device also supports ultra-low-speed operation at 32.768 kHz (30.5 μs instruction time) for RTC and low-power monitoring tasks - all within the same R5F100CCGLA#U0 silicon.

Does the R5F100CCGLA#U0 support in-system programming and secure firmware updates?

Yes, the R5F100CCGLA#U0 supports full in-system programming via its on-chip debug interface and includes self-programming capabilities with boot swap function and flash shield window protection. These features allow safe, field-upgradable firmware deployment while preventing unauthorized access to code memory - essential for maintaining security and reliability in deployed R5F100CCGLA#U0-based systems.

What analog features are integrated into the R5F100CCGLA#U0?

The R5F100CCGLA#U0 integrates a 10-bit successive-approximation ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. It operates across the full 1.6–5.5 V supply range and supports differential input configurations. These analog resources are fully accessible in the R5F100CCGLA#U0's 36-pin WFLGA package without requiring external components for basic sensing applications.

How does the R5F100CCGLA#U0 manage power in battery-operated applications?

The R5F100CCGLA#U0 employs multiple low-power modes - HALT, STOP, and SNOOZE - to minimize energy consumption. In STOP mode with only RTC and LVD active, it draws just 0.57 μA. Its 66 μA/MHz active current and configurable peripheral clocks allow precise power budgeting. The R5F100CCGLA#U0's SNOOZE mode further enables UART or I²C wake-up events without full CPU restart, extending battery life in intermittent-use applications.

Is the R5F100CCGLA#U0 pin-compatible with other RL78/G13 devices in the same package?

Yes, the R5F100CCGLA#U0 shares identical pinout and electrical characteristics with all other RL78/G13 devices in the 36-pin WFLGA package (e.g., R5F100CGGLA#U0, R5F101CCGLA#U0), as defined by Renesas' PWLG0036KA-A mechanical specification. This allows direct substitution within the same footprint when memory or feature requirements change - provided software accounts for differences in flash size, data flash presence, or peripheral enablement in the R5F100CCGLA#U0 configuration.
